The spin modulation is proposed with modulating frequency and amplitude simultaeously, and realized with the array sturcture easily located due to the nanometer size of the spintronics oscillator. In this paper, the dual-channel receiver is deisgned for detecting the spin modulated signal. Resultly, we confirmed the dual-channel recevier well detected the data sent through the spintronics oscillator array, and processed up to 200 kbps on each channel. Distance is limited up to 1 cm due to the low level signal under -60 dBm. The realized dual-channel receiver has the size of $56{ imes}33mm^2$.
